Radio Interference
If it has been determined that a nearby display’s radio signal is interfering, the settings of
the radio receiver or wireless base station inside the display(s) must be changed.
1� To locate the radio receiver or base
station, simply look for the black antenna
sticking out the front of the display.
2� Open the access panel to which the
receiver is attached as described in
Component Locations & Access (p�19) .
3� The radio receiver has a plastic cover
with a window to view status indicators
( Figure 11 ).
Note: While it is necessary for the display
to be powered on to check the
indicators, always disconnect
power before servicing.
4� Remove the four screws in each corner
using a #2 Philips screwdriver and lift off
the cover.
5� Use a small flathead screwdriver to set
the CHAN and BCAST switches to a new
channel and broadcast group (1-8) as
needed. Be sure to always leave FUNC set
to “1”. Refer to Figure 12 .
6� Screw the cover back on and securely
close the access panel.
7� Enter the correct sport code and new
radio settings into the console to test the
radio control. Refer to the appropriate
control console manual listed in Display
Controllers (p�3) .
For more information, refer to the Gen VI
Radio Installation Manual (DD2362277) ,
available online at www.daktronics.com/
